Improvement in lubricators

iMPnovlaMi-:NTl in LuBRicAi-oRs.

The Schedule referred to in thes'e Letters .Patent and-making part ofthe same.

To a?! 'whom ttnayconcerit: n Beit known'that 1,'EnNEs`T VGN Janssen, of the cit-y and county of San Francisco, State of California,

`have invented an e for Axle-Boxes;n and I` do'hereby declare that theI following is afull, clear,`and exact description of the same, reference being had .to the aecompan ying draw- 4ing andto thelet-ters marked thereon.`

The-object of my invention` is to provide angi'ni# prveddevice for economically and etfectually lubri- -catingthe journals orA wearing surfaces of car-axles,

orv other axles 'or shafts that carry the weight of the car or machinery upon their upper surfaces,and have "nobearing below.4 t i My presentinventioni'elatesfto additional improvements in that class' of lubricators shown in Vmy Letr 'teis Patentdated July '5, 1870, andwhifch convey j the oil 'by capillary at-tractioufroin :L suitable i'eser- `.voir, chamber, or recess,to

` y the journals or wearing. surface of the machinery, and ,-"distribute` it upon every part of said-surface by means of strips'or sheets of felt, or other .capillary substance', so arranged that whilebnly j nst suifcientot" the Ac(' nduet ing material iscmployed to answer the purpose required, eve`ry part of the jouinalor wearing-surfacewill be brought l.repeatedly in cont-act. with Vthe said capillary sheets or strips' during the revoliitionsofthe journal or the movements of' theiiiachinery, saidshcetsjloi strips, 'or wicks, acting `.like a brush inl distributing the liibricatingoil, and, like the 'wick of a lamp, y.in conveying -said oil to `the distribiit-iiigLsui-face or brush. i

'lhis invention consists of -a `piecefofwood, or other suitable material, a litt-1e shorter than the journal to which itis to be applied, overwhich is' benta sheet substance, properly secured to -thegwooth and extending oil containedy in ,tr'i'e reservoir below, the upper` surface of the felt being pressed gentlyagainst the lowerf-surfaceof the'journals by springs attached to the under `side of 'the wood, said .springs iesting upon and reacting' from the boti tom of the oil-reservoir.

VIn the drawingn n n `n n n Figure 1 1s a side elevation of .a device embodying i Figure 2 is'an end view of the same.

` 'may be used thatpossessesthe property'of absorbing a liqnidyand conductingt by means of capillary attraction. I

.Bis a rectangular piece of wood, -a little s li'orter than the length of the journal', to the underside of 4which myinvention 'is tobe applied. -I` prefer wood Improved Self-Acting Lubricator is obtainedV and y fashioned` into the required forni, and on account of the facilitywith which the felt maybe secured to it;

but any-other suitable material may be used.

C aretlie nails by which the felt is attached to the wood.

' D aresprings, secured by screws E to the under side of the wood.

r It is obvious that instead of employing springs, constructed as shown in the drawing, spiral springs may be used, and where there is but little room below the journal, I 4prefer to use one or more 4spiral ,'spring's, formed like a bed-spring, in which the `radii of the coils decrease from below upward, or from above and below toward the center of its height in such a mannei' that, when the spring is coinpressed,onecol will close or pass within the other, audoccupy much less `rooin` vertically than other kinds of springs.

i rlhe height of the device should be such that, `when placed under a journal for use, theupper surface F oi -the felt should be caused to slightly press the under side of the journal by thcaction of the springs 'D reacting fromtlie bottom lof the oilreservoir,'and it is evident that when so placed', the .ends G of thc felt would absorb the oil. and convey it Vfrom the reservoiil to the surface 1i1 to he distributed, as with a brush, upon thesurface of the journal.

- H are guides, projecting from each side of the lubricator, formed by driving nails into the wood.

For a vrailroad-car axle-box, the outer extremities f the guides, by coming-in contact with the sidesot the casing or box, will retain t-lie lubricatoi` in its propel' position under the journal. Either one or two pairs of guides, H, niay be used. n

It isobvious. that, instead of nails, the guides H may befoimed in any convenient manner, with transl versc pieces of wood or metal, but I prefer the luse of common-nails, as shown, on accoiiut of simplicity and i the facilityof application.

Having thus describcdniy invention, e

What I claim, and desire to secureby Letters Pat. ent, is-

1. The lubricating device herein described,consist-V ing of lthe springs D, the piece of wood B, and the felt A, or the equivalent of these parts, when secured togetheiyand arranged to operate in a manner substantially as and for the purpose herein described and set forth.

. 2. The lubricating device herein described, when provided with vguides H, or their equivalents, as de scribed.

In testimony wliereofl have hereunto set my hand and seal. y
